Computers and modelling at SCHOLA LUDUS teaching of physics

The SCHOLA LUDUS approach for using computers is presented. The emphasis is on physical modelling, physical process simulations and development of student critical thinking. Students observations and experiences should result in their own descriptions and further predictions, models, graphs, etc.. Hence, the computer is only a necessary complement that should be used after all of these, at the right time with respect to the students readiness, including their skills and knowledge of necessary concepts and theories, to make the knowledge more intensive and operational and, at the same time, to make the advantage of computer usage more clear and convincing.
